Hi,Hello everyone. It's my first question here. I joined the forum because I have a question.Is there any particular research / book on wandering objects in the universe beside articles? I'm interested in clusters of stars that are remnants of an ancient galaxy. Also I wonder if a wandering black hole may one day turn around and go back to it's home galaxy?My interest in these matters is not purely science. I believe stars are connected with human souls. Understanding them may shed good light into human lives.Many thanks in advance and all the best to everyone.Lost galaxy
